Description

The STHV64SW is an integrated circuit which features 64 independent switches. It is

designed for medical ultrasound applications, but can also be used for driving

piezoelectric, capacitive or MEMS transducers, and in industrial application such as

generic high voltage switches.

The STHV64SW comprises a shift register for serial communication, self-biased high

voltage MOSFET gate drivers, high power N-channel MOSFETs, bleed resistance for

each switch, thermal sensor and undervoltage lockout. Moreover, the STHV64SW

includes self-biasing and thermal shutdown blocks. The switches are capable of

providing up to ±3 A peak output current.

Applications

? Medical ultrasound imaging

? NDT ultrasound transmission

? Piezoelectric transducer drivers

? Industrial
